Preventing yellowed collars

Probably the most noob menswear question of all, is there any solution to preventing, or reducing having collars of light coloured shirts turning yellow? I usually don't wash my shirts after each wearing, since this wears them out too quickly, so what other options do I have? Any ways to get out set in stains, or is all hope lost?

First-off, I think euro-style, front-loading washing machines are much gentler on clothes. Secondly, just wash them with fewer items. The less they have to rub against, the less they'll fray.Aside from that you just have to do laundry frequently to avoid any stains setting. When you do wash them, you could use something like Spray-and-wash.

I believe conservatism is race-warfare and culture-warfare, which I find to have horrific outcomes, whereas class warfare is ultimately mostly positive in my opinion (Nameback)

Prior to washing I spray a detergent on collars and cuffs that was designed for soaking in 15 minutes before washing - nothing fancy really, but since I do this I have never seen a trace of dirt on the collars after washing.

Before that I suppose the dirt could have accumulated because it was not completely removed during washing.

If you wash your shirt yourself and discover serious &quot;collar dirt&quot;, pretreat the collar with ox-gall soap (has to be non-fading if it is a coloured shirt) or liquid washing agent/soft soap before putting it in the machine. Let it act for some time on the fabric before you wash it.
Sometimes also gasoline helps as a pretreater, but then again you shoul be careful with coloured shirts.

It's not really dirt. I think the yellowing on collars is caused by a heavy oil, not sweat, that is secreted by the skin. My undershirts eventually get yellow pit stains, and they're washed after every use... I don't like how undershirts look under a dress shirt, but if it wasn't for them, my shirts would have pit stains as well.

I've read things before about using chalk on the insides of collars, and so on.

Well, "collar dirt" was a my creation to describe that mixture of whatever causes the yellowing, I think everyone will have this problem if a shirt worn long enough.
Pretreatment with a liquig washing detergent seems to me quite safe, so I just would try it.
If you think that it is mainly oil, you should try dishwashing liquid, rub it in the yellow places with your fingers and wash it than as you would do normally.

Not sure if you were implying that underarm stains on t-shirts were also caused by heavy oil, but the yellowing's actually from the aluminum chloride found in 99% of over-the-counter deoderants.

You mean anti-perspirants? I didn't know that they caused yellowing, but they did make the pits of my shirts stiffer and left a white coating in the underarm area on darker shirts. I made the switch to the crystal pit stick this winter.

For me, soaking the shirt and then giving the collar, armpits, and cuffs a good brushing with a fingernail brush and bar soap, then leaving the shirt to soak in a plastic grocery bag (bummer for any environmentalists who refuse anything but paper) overnight before washing (Tide grandules with a bit of Oxyclean) has been most effective.

Yep, antiperspirants containing aluminum are what cause armpit staining. I've switched to deodorant I no longer have this problem.
